What is the standard approach to handle 502 Bad Gateway errors when the Genesys Cloud Data Action invokes our ServiceNow REST endpoint via the EU-West-1 region? The payload contains standard conversation context fields, yet the integration consistently fails after three retries despite valid OAuth tokens and correct endpoint configuration. Need to know if this is a timeout issue or a serialization mismatch in the webhook payload structure.
likely a timeout on the sn side since the eu-west-1 to apac hop adds latency. check if your sn instance is dropping the request before it finishes processing.
yeah, that latency hop is usually the culprit, but i’d double-check the payload size too. serviceNow’s default timeout is often 30s, and if you’re dumping the full conversation history in the body, it’ll choke before the gateway even routes it.
i’m migrating similar logic from Five9 and had to strip the payload down to just the essential keys. here’s the architect expression i use to filter the context before sending it to the Data Action:
let minimalPayload = {
"ticketId": data.actionInput.ticketId,
"agentEmail": data.actionInput.agent.email,
"interactionId": data.actionInput.interactionId
};
return JSON.stringify(minimalPayload);
also, make sure your Data Action is set to POST and not GET. GET requests with large bodies sometimes get mangled by the proxy. if you’re still hitting 502s after shrinking the payload, check the ServiceNow glide.rest.message.timeout system property. usually bumping that to 60s fixes the flakiness.

timeout theory makes sense. i bumped the architect data action timeout to 30s and it stopped failing.
"timeout": 30000
sn was just slow. simple fix.
timeout bump helps, but you’ll still hit 502s if the payload exceeds the gateway limit. strip the transcript. just send the call uuid and status.
{
"call_uuid": "${interaction.callUUID}",
"status": "${interaction.status}"
}
sn doesn’t need the whole conversation history.
